Throw out the table.
If you have deep snow, sit on the bike and adjust pressure to have 2 wrinkles (or more if you really need more float). On non-deep snow, have enough pressure to not have wrinkles, but little enough for the tire conforming well to the ground. On pavement, have pressure above the point where you have noticeable more drag.
This algorithm was developed to account for weight, tire material and suppleness, tire width, rim width and temperature. It calculates optimum pressure for the conditions at hand.
